The Constitution Pipeline has been designed to consist of a new 125-mile pipeline with a capacity to transport 650,000 dekatherms of natural gas per day linking the Marcellus Shale with markets in New York and New England.

Northwest Innovation Works (NWIW) and Williams’ Northwest Pipeline have signed a pre-construction agreement for Northwest to construct a three-mile, 24-inch diameter natural gas pipeline and related facilities extending from Northwest’s mainline to NWIW’s proposed methanol production facility planned for the Port of Kalama – all located in Cowlitz County, Washington.

Expansion of Williams’ existing Pennsylvania energy infrastructure to transport 582,400 dekatherms of natural gas supply per day from northern and western Pennsylvania in time for the 2021-22 winter heating season.

To meet the growing demand for natural gas in the North Seattle market area, Northwest has proposed the North Seattle Lateral Upgrade Project (Project) located in Snohomish County in the state of Washington. Northwest has executed firm agreements with Puget Sound Energy (PSE) for the project to expand the delivery capabilities of Northwest Pipeline’s North Seattle Lateral, which serves PSE customers. PSE operates Washington’s largest natural gas distribution system serving nearly 800,000 gas customers in six counties, approximately 25 percent of those are in north King and south Snohomish Counties.

Williams is developing the Northeast Supply Enhancement project to expand the existing Transco natural gas pipeline system by the 2020 winter heating season to provide important gas supply that will help the City reach its clean air goals.

The Southeastern Trail Expansion is designed to provide additional reliable service to utility and local distribution companies located in Virginia, North Carolina, South Carolina and Georgia by winter 2020.
